Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Based on particle swarm optimization, the present invention models the evolution models of biological communities such as mutualism, symbiosis and parasitism, and incorporates the idea of multi-population cooperation, such as figure 1 As shown, a scheduling optimization method for RFID network readers based on the multi-swarm particle swarm algorithm is provided, which can solve the reader-writer conflict caused by the overlap of the reading area or the frequency interference area of the RFID reader-writer, and realizes multiple The population evolves and cooperates with each other at the same time, which has the advantages of strong global search ability, fast convergence speed, and high optimization accuracy.
[0026] The reader conflict in RFID network can be described by graph theory method. For an RFID network with n readers, ...
